My son took apart a broken bbq grill. Left the lid on the grass for two minutes and naturally the dog had to jump in and get soot all over her legs. This is a bit on the greasy side. Would it be safe to use "Dawn" dish detergent to wash her in? I'm thinking, if they can use it on birds, it should work on a dog. Or is there anything else safer?

Joe, as a general rule most shampoos, even 'grease removal' shampoos aren't up to getting off that sort of grease and grime. Dawn is not only safe but it's used by a lot of groomers to get a clean dog.

Yep, I agree with Happy. I know some show groomers who specialize in terriers that show and hunt. Cleaning up an Airedale after a rough hunt to get him show ready...they use Dawn, or lemon Joy for the initial wash. Not only does it cut down on the wash time (you'd need at least two with a regular shampoo) but it rinses out of the coat very well.
